Be it known that I, WILLIS W. PEASLEY, a'

citizen of the United States, residing at Kellerton, in the county of Ringgold and State of Iowayhave inventedcertain new and `useful Improvements in'Furnaces, of which the following is 'a specification, reference being had therein to the .accompanying drawings.

My inventionrelates to an improvement in furnaces ofthe type in which'a coking-chamber is associated with the tire-chamber, where` by coal fed to the former is converted into coke by the heatv generated in the fire-chamber and 4in the latter statefed to said fire-chamber in the desired quantities, the material removed beingcreplaced bya fresh supply ofcoal, this procedurebeing carried on continuously dur- Aextend down or close the front of the space between the -side wall below the arch e, and,

ing the operation of the furnace.

It is the object of the present inventionto increase the efficiency of. this vclass of fur.-

naces, to simplify the const ructionof the` same, and to facilitate their operation.

The invention also contemplates several other desiderata and advantages, as will be appreciated as the invention is better under-v As before premised, the invention conteurplates a furnace having a nre-chamber with acokingchamber arranged above 1 the l same,`

and means forfacilitating thefeedingothe 'coal which'hasbeen 'cokedffrom'thef latter chamberinto the former. y, Thetwo chambers. are arranged'in superimposed relation` and; are formedjbyan.arch-e, which spans aspacel;

inclosed by side walls b,- av4 rear "wallc, a top arch cr, and a half-front'wall c. Each side wall is built of brick and is of any desired c, thickness, said wall being spaced aI suitable 'i distance apart and vpreferably lined with tirebrick. The rear wall c completely closes the backof the furnace and extends from the top to the bottom of thesaine. The top wall is .arranged above or is built in with the upper arch a, whichextends the entire distance from the rear tothe front of the furnace and spans the`.space between the side walls of the same. Intermediate of thepheight of .saidwalls a second arch e is provided, which'spans the space between said walls'v and extends from the rear Vwall cto within a shortdistanccof the front wall'c',.thus leaving aspace between the same, for a purpose .to be describedv hereinafter. The latter wall completely close'sthe front of thefsp'ace or chamber between the two arches 'a and e; but as it is only a half-wall it does not consequently the chamber below said arch is entirely'open at its front end. This latter chamber forms the fire-chamber a.' of the fur5 nace, and in the front thereof an inclined grate 'g is located, which extends from side to side of the same and from its top down to within .a short distance of its bottom. The front of the arch e referred to terminates to the rear of this grate, so 'that the opening between the former and the front wall of the furnace is also, located to the rear of the grate.

In thel front wall c a suitable feeding-opening c2 is provided, designed to be normally closed lby a suitable door c3.

- The operation of the parts of the furnace so far described, assuming thata fire is burning in the chamber a', is as follows: Coal is thrown intovthe chamber c2 through theopening c2 and accumulates upon the top of the arch @which forms a bed for the same.

in thechamber u', and when a fresh supply offuel is required in the latter chamber the :door csisopened-and a part of the coke on the arch e' pulleddor drawn forward overthe front edgeof the latter, when it fallsthrough the openings vc4 onto the grated.) A fres'hsupply `fof lcoalf is then thrown-onto.therea'rofrthe archto replace the material discharged there- 'from'. This procedure is carredcntcgntinu- The gases and smoke generated iii' the coking-chamber discharge therefromthrough an Yously during the operationf;ofthj'e1,furnace.V

This coal U is convertedinto coke by the heat generated IOO opening or aperture c5, provided in the rear of the wall c of the furnace. To consume the smoke and gases to a maximum degree, I provide directly beneath the opening c a corresponding opening c, which communicates with the upper rear end of the fire-chamber and through which the highly-heated gases and products of colnbnstion therefrom discharge and rising commingle with the smoke and gases discharging through the opening c5 and consume the same. To aid combustion in each of the side walls b, a tine i is provided, which opens ont through the top of the furnace,where regulating-dampers m are placed, and these fines communicate with the coking and fire cham bers through openings t" and ft2, leading into the upper part of the same. These fines not only pnt the chambers into communication with the outside air, but also into communication with each other. In each of the lues between the two chambers a regulating-damper is placed.

In the embodiment of the invention illustrated in the views showing a modification of the form of furnace hereinbefore described the front wall of the coking-chamber is of a depth only as great as the length of. the arch c, the front wall being arranged in vertical alinement with the front edge thereof. The side walls of the fire-chamber consequently project ont beyond said front wall, and in feeding the coke to the grate it is drawn ont through the door through which fresh coal is fed to said coking-chamber. As in this form of furnace the grate is also arranged in advance of the front end of the arch e', the material drawn therefrom through the opening c2 Will fall upon this grate.

Vhile the invention as described was primarily intended to be associated with a brickkiln and is more particularly adapted for this purpose, it will be understood that it has a wide range of uses, and its many advantages will be found of value in every situation where this general type of furnace maybe employed.

Having thus fully described my invention, what is claimed as new, and desired to be secured by Letters Patent, is

l. In combination, a furnace having a coking and a fire chamber, an arch forming the division-wall between said chambers extending entirely from the rear wall of the furnace to the front wall thereof, a filling and discharge openingin said front wall, extensions of the side Walls of the fire-chamber projecting beyond the front Wall of the furnace, and an incline grate located in the projecting walls of the lire-chamber and extending in advance of the front wall of the furnace.

2. In combination in a furnace provided with a fire and a coking chamber, an arch forming the division-wall between the same, an inclined grate in the fire-chamber in advance of said arch and a line located in each side wall of thefnrnace in communication with each of said chambers, and with the exterior of the furnace, substantially as described. v

3. In combination in a furnace having alire and a coking chamber, an arch forming the division-wall between the same, an inclined grate in the fire-chamber in advance of said arch, and a flue located in each side wall of the furnace in communication with each of said chambers, said flue extending through the top of the furnace, a damper located on said top and a damper arranged in each flue between said chambers, substantially as described.

In testimony Whereof I allix my signature in presence of two witnesses.
